Kate’s first royal portrait unveiled

London - The first official portrait of Prince William's wife Catherine was unveiled Friday at a London gallery where it was hailed by its subject as “amazing” but slammed by some critics.

The National Portrait Gallery commissioned award-winning artist Paul Emsley to produce the painting of the Duchess of Cambridge, who is expecting her first child this summer, after she became patron of the gallery early last year.

The 31-year-old royal, who attended a private viewing of the painting with her husband on Friday ahead of its unveiling to the public, told the artist: “It's just amazing, I thought it was brilliant.”

Prince William added: “It's beautiful, it's absolutely beautiful.”

But some critics panned the softly-hued work.

Robin Simon, editor of the British Art Journal, told the Daily Mail: “Fortunately, the Duchess of Cambridge looks nothing like this in real life. I'm really sad to say this is a rotten portrait.”

Ben Luke in the London Evening Standard said it was a “gentle, soft-focus image, like a delicately airbrushed photograph or a vaseline-lensed view of a Hollywood star”.

“The Duchess explained that she would like to be portrayed naturally Äher natural self Ä as opposed to her official self,” he said, adding: “She struck me as enormously open and generous and a very warm person.”

Catherine, who last month spent several days in hospital with a severe form of morning sickness, met with the artist and his family following the viewing and was looking well.

The head and shoulders portrait, set on Emsley's trademark dark background, was built up using thin layers of oil paint and glazes, with Kate attending two sittings last summer.
